* genautomata.c (output_internal_insn_latency_func): When writing
the function "internal_insn_latency" to insn-automata.c,
strengthen params "insn" and "insn2" from rtx to rtx_insn *, thus
allowing the optional guard function of (define_bypass) clauses to
expect a pair of rtx_insn *, rather than a pair of rtx.
(output_insn_latency_func): When writing the function
"insn_latency", add an "uncast_" prefix to params "insn" and
"insn2", reintroducing "insn" and "insn2" as rtx_insn * locals
using checked casts from the params, thus enabling the above
change to the generated "internal_insn_latency" function.

logic around the call to overwrite "note" appropriately if
tablejump_p returns non-zero.
(get_last_bb_insn): Introduce local "table", using it in place of
"tmp" for jump table data.
* dwarf2cfi.c (create_trace_edges): Likewise.

* config/arm/arm.c (get_jump_table_size): Strengthen param "insn"
from rtx to rtx_jump_table_data *.
(create_fix_barrier): Strengthen local "tmp" from rtx to
rtx_jump_table_data *.
(arm_reorg): Likewise for local "table".

* config/s390/s390.c (s390_chunkify_start): Likewise.

* config/spu/spu.c (spu_emit_branch_hint): Likewise.

* jump.c (delete_related_insns): Strengthen local "lab_next" from
rtx to rtx_jump_table_data *.

* rtlanal.c (tablejump_p): Strengthen param "tablep" from rtx * to
rtx_jump_table_data **.  Add a checked cast when writing through
the pointer: we know there that local "table" is non-NULL and that
JUMP_TABLE_DATA_P (table) holds.
(label_is_jump_target_p): Introduce local "table", using it in
place of "tmp" for jump table data.
